Which statements are true about the circle shown?
Check all that apply
The diameter of the circle is 30.8 m.
The circumference in terms of it is 30.87 m.
The circumference of the circle can be found using
2 (15.4)
p = 15.4 m
The approximate circumference of the circle
rounded to the nearest tenth is 96.7 m.
A little more than 6 diameters could be wrapped
around the circle.

well okay, i don't really understand it, but i'm gonna try my best. Um, you know what. I can't get it and i'm sorry so maybe go to this website. Cymath.com it gives you the answer right away!

Step-by-step explanation:

step-by-step explanation:

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
